When a power setting table shows a "best economy" and "best power" setting
for a given power level (say 75%) using a given MP and RPM this is just a
starting point, right?

Once the MP and RPM has been set and the leaning done, the actual power
settings would be more like 78% for best power, and 73% for best economy,
wouldn't they? (%'s are just guesses, no science involved).

Thanks in advance.


It probably depends on the power table.

For example, the Mooney Ovation2 has separate tables for Best Power and
Best Economy. The former calls to lean 50°F ROP, and the latter 50°F LOP.

Others that I've seen give you a specific leaning parameter in order to
obtain the power in the table.
